Quote: Would installing valves made from a more heat resistant material help to reduce the chance of burning the valves by running a lean mixture? Seems like a logical solution, but what kind of valve(s) would be more heat resistant?
aluminum pistons will melt before your valves will. burnt valves are usually due to an exhaust leak.That is why they look like they have been cut with a torch. Basically that is what happens. when oxygen is introduced to the exhaust charge.
